I just purchased a 2005 sts. My clock does not work and i have found out the issue concerning this system. I cant get my navigation system to calibrate my location properly does anyone know how to fix this. I was also wondering whats different about a 2008 and newer navigation system on the sts. Would it work in my 2005 i noticed on ebay it states the 2005- 2007 navigation systems are different. Does anyone know whats different would a navigation system from a 2011 work in my 2005.
Thank you for any help.
